Thats got all the specs and reccomendations and stuff....i've got the 15.2 and used the 1500 watt vented reccomendations. if you think i should change anything on the box that would sifnificantly improve it...tell me. The only other thing i want to make sure of is the driver itself has enough clearence on the back (it might get close to the port wall). LMK what you can do, thx.
